Some of todays progress...
Got the last of the wiring I needed out of the Capri. The big one is what plugs into the engine harness and then gets wired to the Festiva's ignition switch wiring. The small bundle of wires pointing north is all I need. Two wires deliver current to the fuel pump, a big blue wire for +12v constant, a wire for switched +12v, a wire for the check engine light, and a couple grounds. That big bundle pointing east is unused.
The smaller plug with the three wires also plugs into the engine harness, but under the hood. Two wires go to the coil connection and provide tach signal, and one goes to the big main power fuse.
I also ordered a new clutch set off ebay, the old one is toast...
The new one is a "XTD Stage 3 Race Clutch", its a 6 puck disc with 'copper ceramic' friction material. Best part is under $160 shipped. I've been told they hold up really well for being a "cheap ebay" setup.
